Reserved

All reserved bits should be written as ‘0’.

7.6.8 Device n Address Register [W]

• Device 1 Address Register 0xC08E

• Device 2 Address Register 0xC0AE

Figure 7-40. Device n Address Register

The Device n Address Register holds the device address assigned by the host. This register initializes to the default address 0

at reset but must be updated by firmware when the host assigns a new address. Only USB data sent to the address contained

in this register will be responded to, all others are ignored.

Address (Bits [6:0])

The Address field contains the USB address of the device assigned by the host.

Reserved

All reserved bits should be written as ‘0’.

7.6.9 Device n Status Register [R/W]

• Device 1 Status Register 0xC090

• Device 2 Status Register 0xC0B0

Figure 7-41. Device n Status Register

The Device n Status Register provides status information for device operation. Pending interrupts can be cleared by writing a ‘1’

to the corresponding bit. This register can be accessed by the HPI interface.

VBUS Interrupt Flag (Bit 15)

The VBUS Interrupt Flag bit indicates the status of the OTG VBUS interrupt (only for Port 1A). When enabled this interrupt will

trigger on both the rising and falling edge of VBUS at 4.4V. This bit is only available for Device 1 and is a reserved bit in Device 2.
